Does Vitiligo Cause White Patches on Skin?

Vitiligo can create sharply defined pale or milky-white areas when pigment-producing cells are reduced or absent. Patches may occur on the face, hands, around body openings, over joints, or in areas exposed to repeated friction. Hair within an affected area can also lose colour. The skin is usually smooth; itch, scale, crusting, or pain suggests that another skin process may be present as well. Colour change can be gradual or become noticeable over a shorter period, and its pattern varies between people.

Arrange a dermatology assessment for new or changing white patches. The clinician may examine the skin closely and ask about family history, other symptoms, and how the colour change developed. Protect lighter areas from sun exposure with clothing and sunscreen because they have less natural pigment. Avoid picking or repeated friction, and use fragrance-free products if the skin feels sensitive. Take clear photographs over time so changes in borders or new areas are easier to discuss.

Book a timely review if patches are spreading, changing quickly, or appearing with hair colour changes. Seek earlier advice when the area is scaly, painful, bleeding, blistered, or persistently itchy, since these features are not typical of pigment loss alone. Ask for medical guidance if colour change follows a new medicine, chemical exposure, or injury. A clinician can also discuss emotional support when visible patches affect confidence, relationships, or daily life.

Could this colour change be vitiligo or another condition? Do I need an examination of other skin or hair? How should I protect the affected areas? What treatment choices fit the location and extent of the patches?
